Discussing the digital transition in urban forests (Lepillé et al., 2017a) in a thematic issue that focuses on this process in mountain spaces may seem incongruous. On the contrary, this article aims to create a dialogue on the frequentations and digital uses in different spaces in order to bring out the common points and differences with regard to the meaning and place that the use of digital technology has taken on in natural spaces.Forest and stadium: is the comparison relevant? We can defend the idea that the forest corresponds to several criteria for defining a stadium within the meaning of the sports code. 1 Indeed, the forest is "an asset belonging to a public or private entity." 2 Moreover, it is to a certain extent "especially designed or used, permanently or temporarily, for the purpose of sporting activity." Forests are equipped, particularly when they are in close proximity to cities, to accommodate sporting activities. Not least, these facilities are either "open to practitioners free of charge or for a fee." Although state forests are free to the public, in other private forests paid activities are offered (tree climbing, paintball, etc.). Beyond the forest, in this sense, all natural spaces, and therefore the mountains, might be compared to stadiums, when these-as we will see in the case of the forest-become, among other things, measuring tools. This detour through the definition of stadiums offers a stimulating metaphor because the leisure sports practices that we studied has led us to consider the forest as a stadium where we measure ourselves − against others or against ourselves − with benchmarks of time and distance that we find in a forest that has become increasingly more mediated by digital tools.
